Leaving a clean wake.

Our Mission

Williams products give people the ability to experience the most diverse, remote and exclusive marine environments in the world, these environments need protecting.

The carbon footprint of using and creating Williams products, has up until now, had a negative impact on the exact environments our product allows you to so easily enjoy. At a time when climate change poses ever greater challenges, Williams is focused on finding sustainable ways for people to experience the earth’s oceans. Our vision is to move towards a climate positive business footprint, built using environmentally friendly materials, powered by zero emission propulsion systems.

UN Sustainable Development Goals

The United Nations General Assembly comprising 193 member governments agreed the Sustainable Development Goals in 2015.

Williams’ selected 4 of the 17 SDG’s to provide a strategic framework for our sustainable actions, that encompasses all aspects of our business operations. We have developed a sustainability strategy that is based on this framework, which will be monitored annually to track performance and undergo a full review in 2027.

We will report on activities in our first annual Sustainability Report in 2024, showing our baseline scope 1 and 2 data for the previous year. We will use this data to track our performance against our decarbonisation plans, with the aim of achieving Net Zero as quickly as possible.


To build resilient infrastructure, promote sustainable industry and foster innovation.

Williams is a leader in the tender boat recreational marine sector in the UK and around the world, we believe that to be a responsible business we need to put sustainability at the heart of our investment strategy. We commit to building clean and resilient manufacturing infrastructure, as part of our business activities to support environmentally sustainable, economic, and social growth within our local community.


To ensure responsible consumption and sustainable production patterns.

Williams Jet Tenders recognise our products are non-essential luxury goods, but we believe they hold the ability to influence sustainable consumption and limit adverse environmental impacts. We design our products with longevity in mind, knowing that they stand the test of time.


To take urgent action to tackle climate change and its impacts.

Williams understands the need to reduce GHG emissions to limit our impact on climate change.

We will measure and report on our Scope 1 and 2 emissions and implement our decarbonisation plan.


To conserve and sustainably use the worlds ocean, seas and marine resources.

Williams endeavours to reduce the effects of using our products in marine environments by creating new innovations that support the latest advances in technology. By supporting ocean conservation programmes, we will promote and find opportunities to contribute to this the vital work.

Reporting & Management

A quarterly sustainability steering group meeting is held to work towards embedding sustainability across the business. Separate project meetings are held to support the application of new technologies through Williams’ research and development team. Our in-house sustainability specialist regularly reviews our progress, providing quarterly updates to board meetings. Our sustainability roadmap and decarbonisation plans will be monitored and reviewed accordingly, to support our good governance processes.

Life Cycle Assessment (LCA)

We are just starting out on the journey to transform our business to one which leaves a clean wake. We are committed to doing things the right way. Our quest for perfection in all we do means that there can be no shortcuts. This is why we initiated, in 2021, a detailed environmental assessment of our complete product range – starting with the TurboJet325 – to really understand the complete environmental impacts of our boats.

We have completed the Life Cycle Assessment for 2 of our products, TurboJet 325 and DieselJet 415, and plan to continue this journey over the coming years. Please view the report for the TurboJet 325 by clicking the button below.

Owning a Williams Jet Tender is a joy.

It opens even greater use of your main craft, allowing exploration of small coves, anchorages, and trips ashore, Williams is making every effort through their Sustainability Roadmap to produce your tender with a low environmental impact in the design, production, delivery, and even the end of life of the tender.

At some point you may wish to sell or trade your tender, or after many years faithful service it may have reached the end of its life, all the steps below will ensure that it remains in tip top condition whilst in your ownership and that will make any part of that process much easier.

Efficient Helming

Your tender is fitted with a fuel management system that allows you to see in real life how much fuel you are using. You were probably having far too much fun to study it closely afloat, but in simple terms when in open water, never forgetting the safety lanyard, accelerating briskly then easing the throttle to a comfortable planning speed of around 20 to 25 knots gives the best economy, by contrast displacement speeds - like when pottering through a crowded anchorage to get to more open water give the poorest so rather surprisingly going faster is actually more efficient. There is a slight caveat, whilst your tender does have amazing sea keeping for its size, your speed does need to consider the comfort of all aboard.

Simple Maintenance

Every contact with sea water produces an increase in the onset of marine growth, so before use ensure the tubes are pumped to the correct pressure 3.6 psi / 250 mb starting with the stern ones first to give the best ride and lower drag. After use a good wash down to remove salt deposits, not forgetting the underside of the hull and perhaps most importantly the jet drive system flushed through with fresh water will make it ready for next time. Tenders by their very nature are often forgotten on the stern or in the tender garage, but expected to perform perfectly when asked, therefore correct maintenance at the recommended service intervals – at a minimum annually. Your local Williams service centre will not only assist with the reliability but additionally keep emissions low and economy high.

Extra Weight

All Williams Jet Tenders have a maximum carrying capacity marked on them and it’s important to never exceed that figure, but any extra weight especially on the smaller models in the range has an adverse effect on performance and economy. This can be in the form of extra items that we keep adding to the boat, so having a clear out is good place to start. Easily missed is water in the bilge areas or the footwells, this needs to be removed either with the bungs if ashore or with a sponge if afloat, make sure the bungs are back in after to always ensure maximum performance, reliability, and stability.
